The LACP Mode in Enterasys or the Port-channel mode in Cisco, have their own algorithms for the priority selection for the slave interfaces involved in the bonding.
As I am a Linux Guy I am more familiar with the Bonding in Linux envoirnment.
We can create bonding in the /etc/sysconfig/network/ifcfg-bond0,here we can define the Master Interface with the IP address and then the slave interfaces involved in the bonding process along with the Mode of the Bonding.

The Switch connected for the bonding also has it's own aggregation algorithm present which must match the with the mode set in the server.

There are 7 modes present in the Linux kernel.

Refer to the Bonding Documentation in the Linux Kernel, it will be available at the pathcat /usr/src/linux-2.6.38/Documentation/networking/bonding.txt | less

Enterasys :
In Enterasys Switches such as N-series, the LACP Lag output Algorithm can be set for the 3 modes
DIP-SIP - Destination IP address/Source IP Address, slave interfaces are assigned on the basis of Source or Destination IP Addresses.
DA-SA - Destination MAC Addess/Source Mac Address, slave interfaces are assigned on the basis of Source or Destination MAC Addresses.
Round-Robin - Equal distribtution from the first slave to all slaves in round-robin fashion
